Chicago style for in-text citations, notes, and bibliography

In Chicago style, use superscript numbers (1) to mark citations in the
text. Place the superscript number for each note just after the relevant
quotation, sentence, clause, or phrase. Type the number after any punctuation
mark except the dash; do not leave space before the superscript.
Number citations sequentially throughout the text. When you use signal
phrases to introduce quotations or other source material, note that
Chicago style requires you to use the present tense (citing Beboutís studies,
Meier points out. . .).

IN THE TEXT

Sweig argues that Castro and Che Guevara were not the only key players in the
Cuban Revolution of the late 1950s.19

After giving complete information the first time you cite a work,
shorten any additional references to that work: list only the authorís
name, a comma, a shortened version of the title, a comma, and the page
number. If the reference is to the same source cited in the previous note,
you can use the Latin abbreviation Ibid. (for ďin the same placeĒ) instead
of the name and title.

The alphabetical list of the sources used is usually titled Bibliography
in Chicago style. If Sources Consulted, Works Cited, or Selected Bibliography
better describes your list, however, any of these titles is
acceptable.

In the bibliographic entry for a source, include the same information
as in the first note for that source, but omit the specific page reference.
However, give the first authorís name last name first, followed by
a comma and the first name; separate the main elements of the entry
with periods rather than commas; and do not enclose the publication
information for books in parentheses. List sources alphabetically by authorsí
last names (or by the first major word in the title if the author is
unknown).

Start the bibliography on a separate page after the main text and any
endnotes. Continue the consecutive numbering of pages. Center the title Bibliography (without italics or quotation marks). Begin each entry
at the left margin. Indent subsequent lines of each entry five spaces
or one-half inch. Double-space the entire list.
